Correction 1982. 1.30 The scope of claims for utility model registration shall be amended as follows. 0 Scope of Claim for Utility Model Registration In a small DC motor in which a magnet body is disposed on the outer circumferential surface of an inner yoke disposed inside a cylindrical moving coil and closely facing the inner circumferential surface of the moving coil, an inner side formed of a hollow magnetic material is used. A small DC motor that is made up of a yoke that is covered with a magnet body that has a cut shape except for the area that approximately corresponds to the area that generates rotational force in the moving coil.
